Trying to make a hyperbolic paraboloid-esq shape, need help

[frv]

I was trying to use the soapskin & bubble tool but it does only seem to generate a flat surface. After that the tools seem not to have any effect. Maybe someone can help me see what I am doing wrong.

you have to enter pressure values ( neg or pos) to get the surface to inflate
